Abstract
⺠A nanoporous Ag/DNA-Cy5/Ag nanoparticle sandwich as SERS substrate was constructed. ⺠dsDNA was used to control the distance between Ag nanoparticle and nanoporous Ag. ⺠A hot spot was formed in the region between closely-spaced nanostructures. ⺠The SERS signal of Cy5 at the hot spot decreased with increasing the length of dsDNA.
